Kruppel-like factors (KLFs) are a group of transcriptional regulators that have recently been identified to exhibit tumor-suppressive function against various gastrointestinal cancers. The present study aims to investigate the expression patterns and prognostic value of KLF-4 in colorectal cancers (CRCs). KLF-4 levels in CRC tissues were examined via immunohistochemistry analysis, real-time ... more

Mutations in codons 12/13 of K-ras exon 2 are associated with reduced benefit from anti-epidermal growth factor receptor antibody treatment for metastatic colorectal cancer (CRC). Here, we evaluated the frequency of K-ras mutations and their relationship with clinicopathological features and treatment outcomes in Saudi Arabian patients with CRC. The genetic status of K-ras was determined in ... more

Recent innovations in the genomic understanding of medulloblastomas have provided new ways to explore this highly invasive malignant brain cancer arising from the cerebellum. Among the four different medulloblastoma subgroups described to date, the sonic hedgehog (SHH) genetic pathway is the pathway activated in the tumorigenesis of medulloblastoma. SHH-related medulloblastomas are usually of ... more

The aim of this study was to evaluate dysregulation of gene expression associated with the cellular stress response in a patient with a post-"warning stroke" depressive disorder confirmed by the presence of a neurophysiological neuromarker through the use of quantitative EEG and event-related potentials. The patient was tested for seven genes associated with the stress reaction: HSPA1A, HSPB1 ... more

Human equilibrative nucleoside transporters (hENT) 1 and 2, encoded by SLC29A1 and SLC29A2, permit the bidirectional passage of nucleoside analogues into cells and may correlate with clinical responses to chemotherapy in patients with colorectal cancer (CRC). The purpose of this study was to evaluate the expression profiles of SLC29A1 and SLC29A2 in human cancer cell lines. Using quantitative ... more

Preeclampsia is a common condition unique to pregnant women. Previous studies have suggested that several cytokines may contribute to defective placental invasion and endothelial damage in this condition. We investigated the influence of four single nucleotide polymorphisms (SNPs) in the promoters of IL-6 (-572G/C, -597G/A, and -174G/C) and IL-10 (-592A/C) on susceptibility to preeclampsia in ... more

Prostate cancer is a common malignancy of the male reproductive-urinary system. MDM2 is an oncogene, whose expression can be regulated by microRNA (miRNA). The present study investigated the expression and correlation of miRNA-509-5p and MDM2 to determine the mechanism of their function in invasion and migration of prostate cancer cells. RT-PCR was performed to detect the expression of miRNA- ... more

Cervical cancer is a common female malignancy of global dimensions. MicroRNAs (miRNAs) play crucial roles in the development, differentiation, proliferation, and apoptosis of tumors. The non-coding RNA MALAT1 participates in various physiological processes that are important for proper functioning of the body. Here, we analyzed the expression of miRNA-143 and MALAT1 in HeLa cells to evaluate ... more

The association between the interleukin-1 beta (IL-1β) C-511T (or rs16944) polymorphism and periodontitis remains inconclusive, even though there have been previous studies on this association. To assess the effects of IL-1β C-511T variants on the risk of development of periodontitis, a meta-analysis was performed in a single ethnic population. Studies, published up to December 2015, were ... more

High plasma homocysteine (Hcy) ​​levels may be responsible for vaso-occlusive episodes and may have acquired and/or genetic causes. This cross-sectional study aimed to investigate the role of methylenetetrahydrofolate reductase (MTHFR; C677T; A1298C) and cystathionine-β-synthase (CBS; T833C/844ins68, G919A) polymorphisms in serum levels of folic acid, vitamin B12 and Hcy, and to verify a ... more
